Disturbing the Peace Under Utah Code: Penalties and Expungement

In Utah, “disturbing the peace” is prosecuted under the disorderly conduct statute at Utah Code 76-9-102, which covers fighting, threatening behavior, unreasonable noise, blocking traffic, refusing a lawful police order to move, and creating a hazardous or physically offensive condition.¹ A first offense is an infraction with only a fine, but the charge jumps to a Class C misdemeanor if you continue after being told to stop, and prior convictions within the past five years push it to a Class B or Class A misdemeanor with real jail exposure.

What the Statute Actually Prohibits

Utah’s law gives prosecutors two separate paths to a charge. The first requires no particular state of mind. You violate the statute if you refuse a lawful police order to move from a public place or an official meeting, or if you create a hazardous or physically offensive condition that serves no legitimate purpose.¹

The second path requires intent or recklessness. You can be charged if you intend to cause public inconvenience, annoyance, or alarm, or if you were aware of a substantial and unjustifiable risk of causing one and ignored it.¹² That mental-state element is what separates a loud celebration from a criminal act. Being annoying is not enough by itself.

Under this second path, the specific acts the statute lists are fighting or violent, threatening behavior; unreasonable noise in a public place or official meeting; unreasonable noise on private property that can be heard in a public place or official meeting; and obstructing vehicle or pedestrian traffic in a public place or official meeting.¹ Each must be paired with the intent or recklessness element.

How the Unreasonable Noise Rule Works

Noise complaints are one of the most common reasons officers write a disorderly conduct citation. The statute does not set a decibel limit, so “unreasonable” is judged on the circumstances.¹

Time of day carries a lot of weight. Music at a moderate volume on a Saturday afternoon probably does not qualify; the same volume at 2:00 a.m. in a residential neighborhood almost certainly does. Location matters too. Sound that blends into a commercial district can be clearly disruptive on a quiet residential street. Duration counts as well: a single burst of loud sound is less likely to draw a charge than sustained noise over a long stretch. The test is objective, based on what an average person would find disruptive, not on the sensitivity of one particular neighbor.

Where the Law Reaches

Most of the prohibited acts have to happen in a public place or at an official meeting. The one exception is noise. A loud party inside your own home can still support a charge if the sound is clearly audible outside in a public area.¹

“Official meeting” is defined broadly enough to include legislative sessions, committee meetings, and meetings of entities created by the Utah Constitution or state code, so disrupting a city council meeting falls within the statute even though the room is not a traditional public space.¹

Penalties and How They Escalate

Utah uses a tiered system, and the step-ups come fast.

Infraction: The Baseline

A baseline violation is an infraction, meaning a fine only and no jail time.¹³

Class C Misdemeanor: Continuing After a Warning

If someone asks you to stop and you keep going, the charge becomes a Class C misdemeanor, carrying up to 90 days in jail and a fine of up to $750.¹⁴ This is the scenario behind most “disturbing the peace” arrests: a warning, continued behavior, then a citation or arrest.

Class B and Class A: Repeat Convictions

If you continue after a warning and you have one prior disorderly conduct conviction within the past five years, the offense becomes a Class B misdemeanor, with up to six months in jail and a fine of up to $1,000. Two or more prior convictions within five years make it a Class A misdemeanor, with up to 364 days in jail and a fine of up to $2,500.¹⁴³

Courts routinely add surcharges and administrative fees on top of the statutory fine, and attorney fees for a misdemeanor defense add more. The numbers in the statute are a floor, not a ceiling.

Aggravated Disorderly Conduct on Streets and Highways

A separate statute, 76-9-102.1, applies when the disruption is blocking traffic on a major road. You commit aggravated disorderly conduct if you intentionally, knowingly, or recklessly obstruct vehicle or pedestrian traffic on a street or highway with a speed limit of 40 mph or higher, or at least two lanes in the same direction, and you refuse a lawful police order to move.⁵

A first offense here starts at a Class B misdemeanor, with up to six months in jail and a fine of up to $1,000. A second conviction within one year is a Class A misdemeanor, with up to 364 days in jail and a fine of up to $2,500.⁵⁴ The baseline is higher because blocking high-speed or multi-lane roads creates an immediate safety risk.

Lawful Firearm Carry Is Not Enough

Utah law specifically protects lawful carriers. Simply carrying or possessing a holstered or encased firearm, openly or concealed, is not disorderly conduct by itself. A charge requires additional behavior or circumstances that would lead a reasonable person to believe the firearm was carried with criminal intent.¹ Someone lawfully carrying a holstered handgun cannot be charged under this statute unless there is something threatening or disruptive beyond the mere presence of the weapon.

Speech, Protest, and Police Encounters

The First Amendment limits how broadly Utah can apply the statute to what people say. The U.S. Supreme Court has held that speech can be punished as “fighting words” only when the words, by their very utterance, tend to incite an immediate breach of the peace.⁶ Later decisions narrowed that category further, so speech that merely invites dispute or causes unrest stays protected.

In practice, yelling profanity at a police officer is generally not enough to sustain a disorderly conduct charge. Verbally protesting police action, even in crude or insulting language, is protected speech. The line moves when words become a direct personal threat or an invitation to physical violence, or when behavior crosses into physically obstructing officers or refusing a lawful order. Recording police in public is likewise protected, though you cannot physically interfere with officers while doing it. If the only evidence against you is offensive speech without any threatening or obstructive conduct, the charge is vulnerable to a constitutional challenge.

Getting a Conviction Off Your Record

A disorderly conduct conviction does not have to be permanent. Under Utah’s automatic expungement statute, an infraction or Class C misdemeanor conviction becomes eligible five years after adjudication, and a Class B misdemeanor requires a six-year wait.⁷ When automatic expungement applies, the court issues the order without you filing a petition, provided the case qualifies and the prosecutor does not object.

Eligibility turns on your full criminal history, not just the disorderly conduct case. Utah’s Bureau of Criminal Identification reviews records from every state, and you can be disqualified by too many combined convictions, unpaid restitution, or current probation or parole status.⁸ If automatic expungement does not fit your situation, Utah also allows a petition-based process with shorter waiting periods in some cases, which requires paperwork and may involve a hearing.

Even while you wait for expungement, a conviction can show up on background checks for employment, housing, and professional licensing. Resolving a charge favorably at the outset, whether through dismissal, a plea in abeyance, or a reduction to an infraction, avoids years of answering for it later.
